This Yokomo D-148 bearing set is made to upgrade assembled Drift Racer drift kits by replacing worn bushings or bearings in wheel hubs and steering supports. The bearings lower rotational drag and help deliver smoother, more repeatable slides during tuning sessions.
Installation is straightforward: remove existing retainers from the front and rear hubs and the steering support, press the correct bearings into place, and reassemble using the original hardware. Apply light metal-compatible grease sparingly where axial damping is desired, and avoid excessive torque on hub fasteners to prevent bearing preload.
Tuning advice: using full metal bearings such as the D-148 reduces wheel play and sharpens steering return, aiding consistent throttle-to-angle transitions. Remember that bearings influence free-rolling feel and input feedback rather than altering motor output or suspension geometry.
